The Windows headers that come with Phobos are extremely incomplete.
Try the WindowsApi bindings project instead:

That should be: WS_VISIBLE | WS_CHILD.

You need a header module that imports the function. Try the vfw.d module 
at the project Jarrett pointed you to.


 
 my compile comman is:
 dmd webcam.d gdi32.lib advapi32.lib


You'll also need vfw32.lib, which isn't part of the DMD distribution, 
but will be on your system if you've downloaded the Platform SDK - in 
which case, you'll need to run it through coffimplib 
(ftp://ftp.digitalmars.com/coffimplib.zip).

Huh? You just run 

  coffimplib -f vfw32.lib

and specify the .lib on your build command line - something like:

  dmd webcam vfw32.lib

Hi John,

Thank you.I have win2003 SDK+vc++2008 EX installed in my machine.When I tried
the winsamp.d in the example folder of dmd(ver2031):

/>coffimplib -f vfw32.lib
/>dmd winsamp.d gdi32.lib vfw32.lib winsamp.def
** also tried bud winsamp.d gdi32.lib vfw32.lib 

I got below error:

Those are warnings, not errors. Ignore them, it will compile anyway.
